Mysql работает не один, а в lampp/xampp

Я только начал веб-разработку на Ubuntu в ядре php и laravel Framework. Я установил php и все зависимости, но mysql не работает индивидуально, а работает внутри lampp

поэтому я начал с того, что дал следующую команду

mysql -u root -p

и я получаю следующий ответ (то же самое для запуска только 'mysql' и 'sudo mysql')

 ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Также, когда я захожу в /var/run, нет папки с именем mysqld

cd /var/run/mysqld
bash: cd: /var/run/mysqld: No such file or directory

Смотрите это тоже

cd /var/run 
aq@DevilsBook:/var/run$ ls
acpid.pid     console-setup  dhclient-wlo1.pid  initctl      mount           rsyslogd.pid       sudo        user
acpid.socket  crond.pid      dmeventd-client    initramfs    network         sendsigs.omit.d    systemd     utmp
alsa          crond.reboot   dmeventd-server    lock         NetworkManager  shm                thermald    uuidd
apache2       cryptsetup     fsck               log          php             snapd-snap.socket  tmpfiles.d  wpa_supplicant
avahi-daemon  cups           gdm3               lvm          plymouth        snapd.socket       udev
blkid         dbus           gdm3.pid           lvmetad.pid  pppconfig       spice-vdagentd     udisks2

Кроме того, в папке /var/lib есть папка с именем mysql и mysql-upgrade.

Тогда я попробовал команду запуска службы mysql, и это заняло так много времени

sudo service mysql status
[sudo] password for aq: 
● mysql.service - MySQL Community Server
   Loaded: loaded (/lib/systemd/system/mysql.service; bad; vendor preset: enable
   Active: inactive (dead)

[1]+  Stopped                 sudo service mysql status

и запустить ту же команду без sudo, и я получаю

Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.

После этого я вижу статус systemctl mysql.service и результат был

[2]+  Stopped                 systemctl status mysql.service

В конце я запустил journalctl -xe

Хотя mysql работает в лампе, смотрите результат запуска lampp sudo /opt/lampp/lampp start

aq@DevilsBook:~$ sudo /opt/lampp/lampp start
[sudo] password for aq: 
Starting XAMPP for Linux 7.2.13-0...
XAMPP: Starting Apache...fail.
XAMPP:  Another web server is already running.

Как найти папку и пакет, чтобы устранить эту проблему?
